GENERAL DESCRIPTIONThe IAMA – Universal Signal Conditioning Module Series can isolate and

convert over 100 combinations of analog signal ranges. The IAMA3535 converts and transmits signals linearly proportional to the input, while the IAMA6262 transmits the scaled square root of the input signal. This allows the IAMA6262 to provide a signal that is linear to flow rate in applications utilizing a differential pressure transducer.

DIP switch range selection eliminates the need to order and stock different modules for each input and output signal range, and allows quick and convenient setup for over 100 standard signal conversions. By utilizing the Field mode of calibration, the user can customize the input and output scaling for odd applications, including reversal of the output relative to the input.

In addition to the conversion capabilities, the IAMA modules feature optically isolated Input/Output signal circuits and transformer isolated Power to Input, Power to Output circuits.

The modules’ overall full scale accuracy typically exceed 0.05% depending upon range selection and scaling. The microprocessor based design provides ease of field scaling and the onboard E2PROM stores scaling values for future recall. Both models come factory precalibrated for all input and output ranges. Factory or custom field scaling can be selected by a simple mode switch change. The IAMA can be factory recalibrated in the field if desired.

The modules’ environmental operating temperature range is -20°C to +65°C. DIN rail mounting saves time and panel space. The units are equipped with universal mounting feet for attachment to standard DIN style rails, including top hat profile rail according to EN50022 - 35x7.5 and 35 x 15 and G profile rail according to EN50035-G32.

MODULE ISOLATIONIAMA modules feature “3-Way” Signal Isolation. The 3-Way isolation is a

combination of optical and transformer isolation. The optical isolation provides common mode voltage (CMV) isolation up to 1.5 kV between the sensor input and the process signal output. The IAMA’s power is isolated from the sensor signal input and the process signal output by a DC/DC transformer isolation circuit.

OVERVIEWThe IAMA3535 continuously monitors a voltage or current input and

provides a linearly proportional voltage or current output, while the IAMA6262 transmits the scaled square root of the input signal. This allows the IAMA6262 to provide a signal that is linear to flow rate in applications utilizing a differential pressure transducer. Both units have two modes of operation known as Factory and Field modes. Factory mode is used when the default input and output ranges are suitable. Field mode can be independently selected for both the input and output, and allows the user to custom calibrate, or scale the signal. If Factory mode is selected, the IAMAs use factory presets for the selected input or output range. If Field mode is selected, the IAMAs can be custom scaled within a selected input or output range. Field mode also allows the IAMA to reverse its output in relation to its input.

The units are factory precalibrated for minimum and full scale for all input and output ranges. The factory calibration values are permanently stored in E2PROM and should not be changed in the field, unless unacceptable error or a factory checksum error occurs. See Factory Recalibration for details. Field scaling is achieved by applying minimum and full scale values from a calibration source and storing the values by a single DIP switch transition. Field scaling is available for all input and output ranges and the values are permanently stored in E2PROM until reprogramming occurs.

After field scaling, the IAMAs can be changed between Factory and Field modes for a particular range, which restores the respective setting. The Factory and Field E2PROM locations contain the same calibration values when the

IAMA is received from the factory. Therefore, until the IAMA is field scaled, factory and field modes perform identically. See SCALING PROCEDURE for detailed instructions on field programming the IAMA.

The units can be scaled to any minimum scale and full scale values within the extent of the selected range. The closer together the minimum and full scale values are to each other, the less accurate the signal will be. For example, if the 0 to 1 V input range is selected, and the unit is scaled for 0 to 0.5 V, the signal has the same resolution as the 0 to 1 V range. Since this resolution will be two times the percentage of span for 0.5 V, more accuracy can be achieved by using the 0 to 0.5 V range.

The input may exceed the full scale value for the selected range by 10% of span, but the IAMA will not update the output beyond 10% over range.

The red and green LED’s indicate the status of the modules during scaling and normal operation. Table 1, LED Indications, details the LED indications for various unit conditions.

The IAMA – Signal Conditioning Module Series is designed for use in industrial environments. Suppressor diodes protect both input and output circuits from wiring errors and transient high voltage conditions.

INPUTSThe IAMAs accept a full range of process signal inputs and isolate and

convert these signals to common industrial control signals. The input signal combinations are configured by making specific DIP switch selections on the 10 position DIP switch.

OUTPUTSAs with the input choices, the process signal output of the modules is DIP

switch selectable. A 1 position DIP switch is used to select between the 1 mA/20 mA output ranges. The maximum output current signal is 22 mA with ≤600 Ω output resistance and the maximum output voltage signal is 11 V with ≥1 KΩ output resistance.

ZERO AND SPANThe input zero and span are set by first applying the minimum value then

transitioning S1-2 to store that value. Next, the full scale value is applied and the DIP switch transition stores the value. The output scaling is performed in a similar manner but the output is driven to the desired minimum and full scale values by the calibration source applied to the input. S1-1 is used to store the minimum and full scale output values.

The span is defined by: span = (full scale - minimum scale).

ILLEGAL RANGE SELECTIONS AND CHANGESThe ranges should only be selected before power is applied. If an invalid input

or output range is selected when power is applied the output is set to approximately 0 VDC and the red LED indicates the error according to Table 1. Power must be removed and valid ranges selected for the IAMA to operate properly.

If S1 switches 3 through 10 are changed while the IAMA is operating, the red LED indicates a range change according to Table 1, LED Indications and the output goes to the previously stored range minimum scale value. Normal operation will be resumed if the switches are placed back in the previous positions or power is removed and restored.

CHECKSUM ERRORSA checksum is performed every time power is applied to the IAMA. If a

checksum error occurs, the LEDs will indicate where the error occurred according to Table 1, LED Indications. Operation with a checksum error is not recommended but can be done in critical situations. If an error occurs, re-calibration of the field or factory ranges to be used must be performed.

If a field checksum error occurs, the IAMA will operate only in factory mode. If a factory checksum occurs, the IAMA will operate only in a previously calibrated field mode. Do not perform a field scaling until the factory checksum is cleared. Since a checksum error is a high priority LED indication, the LEDs will indicate the error until it is cleared. This will exclude other LED information.

EMC INSTALLATION GUIDELINESAlthough Red Lion Controls Products are designed with a high degree of

immunity to Electromagnetic Interference (EMI), proper installation and wiring methods must be followed to ensure compatibility in each application. The type of the electrical noise, source or coupling method into a unit may be different for various installations. Cable length, routing, and shield termination are very important and can mean the difference between a successful or troublesome installation. Listed are some EMI guidelines for a successful installation in an industrial environment.1. A unit should be mounted in a metal enclosure, which is properly connected

to protective earth.2. Use shielded cables for all Signal and Control inputs. The shield connection

should be made as short as possible. The connection point for the shield depends somewhat upon the application. Listed below are the recommended methods of connecting the shield, in order of their effectiveness.a. Connect the shield to earth ground (protective earth) at one end where the

unit is mounted.b. Connect the shield to earth ground at both ends of the cable, usually when

the noise source frequency is over 1 MHz.3. Never run Signal or Control cables in the same conduit or raceway with AC

power lines, conductors, feeding motors, solenoids, SCR controls, and heaters, etc. The cables should be run through metal conduit that is properly grounded. This is especially useful in applications where cable runs are long and portable two-way radios are used in close proximity or if the installation is near a commercial radio transmitter. Also, Signal or Control cables within an enclosure should be routed as far away as possible from contactors, control relays, transformers, and other noisy components.

4. Long cable runs are more susceptible to EMI pickup than short cable runs.5. In extremely high EMI environments, the use of external EMI suppression

devices such as Ferrite Suppression Cores for signal and control cables is effective. The following EMI suppression devices (or equivalent) are recommended:

Fair-Rite part number 0443167251 (RLC part number FCOR0000)Line Filters for input power cables:

Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000)6. To protect relay contacts that control inductive loads and to minimize radiated

and conducted noise (EMI), some type of contact protection network is normally installed across the load, the contacts or both. The most effective location is across the load.a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide

varistor (MOV) across an AC inductive load is very effective at reducing EMI and increasing relay contact life.

b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor switch, care must be taken not to exceed the breakdown voltage of the transistor when the load is switched. One of the most effective ways is to place a diode across the inductive load. Most RLC products with solid state outputs have internal zener diode protection. However external diode protection at the load is always a good design practice to limit EMI. Although the use of a snubber or varistor could be used.RLC part numbers: Snubber: SNUB0000 Varistor: ILS11500 or ILS23000

7. Care should be taken when connecting input and output devices to the instrument. When a separate input and output common is provided, they should not be mixed. Therefore a sensor common should NOT be connected to an output common. This would cause EMI on the sensitive input common, which could affect the instrument’s operation.

Visit RLC’s web site at http://www.redlion.net/Support/InstallationConsiderations.html for more information on EMI guidelines, Safety and CE issues as they relate to Red Lion Controls products.

WIRING CONNECTIONSAll conductors should meet voltage and current ratings for each terminal.

Also cabling should conform to appropriate standards of good installation, local codes and regulations. It is recommended that power supplied to the unit be protected by a fuse or circuit breaker. When wiring the unit, use the numbers on the label to identify the position number with the proper function. Strip the wire, leaving approximately 1/4" (6 mm) of bare wire exposed. Insert the wire into the terminal, and tighten the screw until the wire is clamped tightly.

POWER AND OUTPUT CONNECTIONSPower

Primary power is connected to terminals 2 and 3 (labeled VDC- and VDC+). For best results, the Power should be relatively “clean” and within the specified variation limits. Drawing power from heavily loaded circuits or from circuits that also power loads that cycle on and off, should be avoided.

Current OutputWiring for a current output is connected to terminals 1 (IOUT-) and 4 (IOUT+).

DIP switch S2 should be set for the desired full scale output current. (20 mA = ON; 1 mA = OFF).

Voltage OutputWiring for a voltage output is connected to terminals 5 (VOUT-) and 6

(VOUT+).

Note: Although signals are present at voltage and current outputs at the same time, only the selected range is in calibration at any one time.Example: A 0 to 10 VDC output is selected. The voltage level present at the

voltage output terminals is in calibration, but the signal appearing at the current output terminals does not conform to any of the current output ranges.

INPUT CONNECTIONSCurrent Input

Wiring for a current input is connected to terminals 10 (IIN) and 12 (INPUT COMMON).

Voltage InputWiring for a voltage input is

connected to terminal 12 (INPUT COMMON) and one of the three available voltage terminals listed below, depending on maximum input voltage.

Terminal 7: 1 VDC max.Terminal 8: 10 VDC max.Terminal 9: 100 VDC max.

SCALING PROCEDUREThe accuracy of the IAMA is dependent on the accuracy of the calibration source and the voltage

or current meter used in the scaling process.If an out of range (see Table 1 for LED indications) or illegal (full scale less than minimum scale)

scaling is attempted, the factory calibration values will be stored in place of the field values. This will prohibit erroneous operation of the IAMA. The scaling procedure will have to be repeated.

The final storage of the zero and full scale values to E2PROM is not done until the last transition of the mode/calibration DIP switches (S1-1 or S1-2). Therefore, the scaling can be aborted any time before the full scale value is saved. This is accomplished by cycling power to the IAMA. The IAMA will restore the factory or previous field scaling values at power up depending on the setting of the DIP switches. See Mode Selection for more detailed instructions for selecting factory and field modes at power up. See Table 2 and 3 for the input and output range DIP switch settings.

2.3 Set Input Range switches (S1 switches 6 through 10) to the desired input range (See Table 3). Select the lowest possible range that will support the desired maximum signal. Example: if the desired span is 20 mV to 85 mV, the best range selection is 0 to 100 mV. The 0 to 200 mV will also suffice, but the accuracy will be reduced. (0 to 10 VDC range shown).

4.1 Remove power.

4.2 For voltage output scaling, go to Step 4.4. For current output scaling, continue at Step 4.3.

4.3 Set 20 mA/1 mA switch (S2) to desired full scale output.(20 mA - on; 1 mA - off)

4.4 Set Output Field/Fact. switch (S1 switch 1) to the off position.

4.5 Set Output Range switches (S1 switches 3, 4, and 5) to the desired Output Range (See Table 2). Select the lowest possible range that will support the desired full scale output. Example: if the desired span is 1 V to 4 V, the best range selection is 0 to 5 V. (0 to 5 VDC range shown)

4.6 Connect volt or current meter to appropriate IAMA output terminals.Terminal 6: + VoltageTerminal 5: - VoltageTerminal 4: + CurrentTerminal 1: - Current

4.7 An input signal is required to complete output scaling. If previous scaled input is used (completed in Step 2.0), Input Field/Fact. switch (S1 switch 2) and Input Range switches (S1 switches 6 through 10) must remain in the same positions. If another signal source is used, set Input Field/Fact. switch (S1 switch 2) to off position and Input Range switches (S1 switches 6 through 10) to the desired input range (See Table 3).

4.8 Connect input signal source to the correct input terminals based on the maximum signal input.

Terminal 7: max. signal input 1 VDCTerminal 8: max. signal input 10 VDCTerminal 9: max. signal input 100 VDCTerminal 10: max. signal input 100 mATerminal 12: signal common

4.9 Apply power to the IAMA and allow a warm up period of five minutes.

4.10 Set Output Field/Fact. switch (S1 switch 1) to the on position.The Red and Green LEDs will alternately blink.If Red LED blinks slowly, increase signal until Red and Green LEDs alternately

blink.

4.11 Adjust the input signal until the desired * minimum output level is displayed on the volt or current meter.The Red and Green LEDs will alternately blink.

4.12 Set Output Field/Fact. switch (S1 switch 1) to the off position. The Red and Green LEDs alternately blink.If the signal is equal to or below the minimum limit of the selected range, the Red

LED blinks slowly and the Green LED turns off. Removing power aborts scaling. Start over at Step 4.1.

4.13 Adjust the input signal until the desired * maximum output level is displayed on the volt or current meter.

4.14 Set Output Field/Fact. switch (S1 switch 1) to the on position. Red LED extinguishes and Green LED becomes solid. Your scaled values are now

saved and will be recalled if the Output Field/Fact. switch (S1 switch 1) is in the on position when power is applied.

4.15 Output scaling is complete.

* If the minimum output is higher than the maximum output the module reverses its output behaviour accordingly.

The following list outlines conditions that are unique to factory recalibration:1. Unlike the field scaling procedures, there are no software under and over

range indications while performing a factory recalibration. Therefore, care must be taken to insure the selected range extents are not exceeded. The minimum scale and full scale calibration values must be set to the extents of the range being calibrated.For example: If the Input Range DIP switches are set for the 4-20 mA

range, minimum scale must be set at 4 mA, and full scale must be set at 20 mA.

2. At least one input calibration must be completed before calibrating any output range. When calibrating the input voltage range, it is recommended that a range above 1 V be used to provide better accuracy.

3. If multiple input or output ranges are to be calibrated, DO NOT REMOVE POWER TO CHANGE THE RANGE. Place the appropriate Field/Fact. DIP switch; S1-1 for outputs, and S1-2 for inputs to the down position, and set the remaining DIP switches for the range to be calibrated. Note: Be sure to change the terminal wiring to match the Input or Output range DIP switch settings before performing the calibration procedure. Set calibration source to 0 V or 0 mA before changing wiring.

INPUT RECALIBRATION1. To enter the factory calibration mode, set switches S1-1 and S1-2 down, S1-3

through S1-5 up, and S1-6 through S1-10 down.2. Connect a signal source to the correct input terminals based on the maximum

signal input to be calibrated. If an output range will be calibrated after the input range is calibrated, connect a voltage or current meter to the appropriate output terminals at this time.

3. Apply power to the IAMA. After the version number indication, the green LED will flash rapidly for 2 seconds indicating the factory calibration mode has been entered. Allow the IAMA to warm up for 5 minutes minimum and follow the manufacturer’s warm up procedure for the calibration source.

4. Set the Input Range DIP switches to the desired input range according to Table 3.

5. Complete Steps 2.6 through 2.10 of Input Scaling Using Field Configuration. Note: There will be no over or under range indication of the LED’s during this procedure, so use care not to exceed the range extents.

6. If an output is to be calibrated, continue from #2 of Output Recalibration below. If no further input or output calibration is to be completed, return S1-1 and S1-2 to the down position and remove power from the IAMA. Apply power and check for accurate operation of the newly calibrated range or ranges.

OUTPUT RECALIBRATION1. Complete 1 through 5 of the input recalibration procedure for at least

one range.2. For current output, set 20 mA/1 mA switch (S2) to desired full scale output.

(20 mA - on; 1 mA - off)3. Set Output Field/Fact. switch (S1 switch 1) to the off position.4. Set the Output Range DIP switches to the desired output range according to

Table 2.5. Complete Steps 4.10 through 4.14 of Output Scaling Using Field

Configuration. Note: There will be no over or under range indication of the LED’s during this procedure, so use care not to exceed the range extents.

6. If no further calibration is to be completed, return S1-1 and S1-2 to the down position and remove power from the IAMA. Apply power and check for accurate operation of the newly calibrated range or ranges.

RECALIBRATING FACTORY STORED VALUES

WARNING: Read the complete procedure at least once before attempting to recalibrate the factory values. This procedure should only be performed due to factory checksum error or unacceptable error. This procedure should be performed by qualified technicians using accurate calibration equipment.

TROUBLESHOOTINGFor further technical assistance, contact technical support at the appropriate company numbers listed.

INSTALLATIONThe unit is equipped with a universal mounting foot for attachment to standard DIN style mounting rails, including G profile rail

according to EN50035 - G32 , and top hat (T) profile rail according to EN50022 - 35 x 7.5 and 35 x 15. The unit should be installed in a location that does not exceed the maximum operating temperature and provides good air circulation. Placing the unit near devices that generate excessive heat should be avoided.

G Rail InstallationTo install the IAMA on a “G”

style DIN rail, angle the module so that the upper groove of the “foot” catches under the lip of the top rail. Push the module toward the rail until it snaps into place. To remove a module from the rail, push up on the bottom of the module while pulling out and away from the rail.

T Rail InstallationTo install the IAMA on a “T”

style rail, angle the module so that the top groove of the “foot” is located over the lip of the top rail. Push the module toward the rail until it snaps into place. To remove a module from the rail, insert a screwdriver into the slot on the bottom of the “foot”, and pry upwards on the module until it releases from the rail.

APPLICATIONCost efficiency measurements of a printing company included the

reduction of bulk stock of the various inks used in their printing processes. The company currently had various ink flow and level devices with different current and voltage outputs and wanted to record these measurements into a control room PC. Several IAMA Universal Signal Conditioning Modules were the answer. The IAMA’s universal input allowed for easy signal conditioning of the various output signals to the required PC’s Bus Board 0 to 10 VDC input signal. The factory calibration settings of the IAMA could be used with the devices in which the flow and level pressure was linear to the signal. The IAMA could also be scaled utilizing the field calibration method with the devices where pressure affected the signal slope specifications. In this case, the IAMA’s re-transmitted 0 to 10 VDC output was field calibrated, negating the expense and time required to rewrite the PC’s software parameters. In addition to accepting multiple signal types and field calibration features, the IAMA also provides the necessary electrical isolation between the control room PC and the hazards of the printing floor electrical noise.
